Just pulled 318 out of 1986 W-150 and replacing it with crate magnum 360 from ATK. Re-using the 727 transmission. Had it rebuilt. The transmission shop also swapped my converter for an externally balanced TQ??? Is this correct?
If you have externally balanced TQ can you use neutral Flex plate? Or does the Flex Plate have to be balanced?
Sorry for the confusion on my part.....new to this, trying to fix up my dads old truck.
